Q1. I curently have a Vivitar 550FD M/P/O dedicated electronic flash unitI used on my Minolta X700. I have just ordered the KM DiMAGE Z3. Does anyone know if "other" flash units (like the Vivitar 550FD M/P/O) are compatable with the Z3? OR Is the Z3 only compatable with the KM flash units? Any info specific to my new Z3 would be appreciated.

Q2. I also ordered a standard 1GB SanDisk SD memory card. I called KM before I ordered it to ask if the camera took advantage og the Ultra II cards. The "well informed expert" at KM told me that the Z3 did not operate any differently with an Ultra II card and I should save my money. Any info?
